For a variety of reasons, we're considering the switch from disposables to cloth with flushable inserts. I'd been eyeing gdiapers with their flushable insert but then learned about having to use a stick to swish and break up the insert in the toilet. I'd like to avoid this. Does anyone have experience with GroVia or Flip with the flushable inserts? Any other flushable inserts that are proven successful, ie, don't clog up your toilet?
